The LDC requires a voltage supply within 2.7 V and 3.6 V. A multilayer ceramic X7R bypass capacitor of 1 μF between the VDD and GND pins is recommended. If the supply is located more than a few inches from the LDC, additional capacitance may be required in addition to the ceramic bypass capacitor. A ceramic capacitor with a value of 10 μF is a typical choice.
The optimum placement of bypass capacitors is closest to the VDD and GND terminals of the device. Care should be taken to minimize the loop area formed by the bypass capacitor connection, the VDD pin, and the GND pin of the IC. See Figure 60 for a layout example.
